Kajian Vaksin Avian Influesa (AI) pada Ayam Buras dengan Sistem Kandang Kurung di Gunung Kidul Yogyakarta

Avian influenza (AI) is highly pathogenic desease in local chicken. Avian influenza (AI)<br />vaccine is one of choice to prevent AI desease. The purpose of these study was to determine the effectiveness of AI vaccine in local chicken at the enclosure cage system in Gunung Kidul, Yogyakarta. A total of 110 local chicken consist of 100 hen and 10 cock were used in these study. The chicken was stored in cage of bamboo that have a measurement of 5 x 4 m2 include 10 hen and 1 cock in cage respectively. The vaccine used in these study was 2 kinds of commercial AI vaccine (A) and local AI vaccine (B). Vaccine with 0.5 ml dose was administrated by intramuscular (i.m) in 55 local chicken respectively. Re-vaccination was administrated after 2 month first vaccination. Examination of antibody titer AI was performed at month 2, 3, 4, 5 and 6 with chicken blood sampling collection via the brachial vein in the wing. Avian influenza vaccine commercial A and local B were protective in local chicken with enclosure cage system after 2 month vaccination and followed by booster.<br />Key words: Avian influenza (AI), vaccine, local chicken

Avian diversity during rehabilitation stage of Chimdi Lake, Sunsari, Nepal

Avian diversity of Chimdi Lake during rehabilitation stage was studied. 109 species of birds belonging to 34 families were recorded. Maximum 64 species were recorded in March 200 4 and 20 species recorded in July 2004.Out of total; bird species 33.94%were migratory, 25.68% were resident, 24.77% were winter visitors and 15.96%were summer visitors. On the basis of abundance, 41.28%were scarce, 22.9 % were occasional, 21.1%were fairly common and 14.6%were common. The Lake area was found to be rich in avian diversity although the Lake was not fully rehabilitated.

Detection of avian rotavirus-like virus in broiler chickens in Bangladesh

The presence of rotavirus infection in broiler chickens (1-2 weeks old) was studied. A total of 232 faecal specimens were collected during the period from July to September 2004 and examined by polyacrylamide gel electrophoresis and silver staining (PAGE-ss) technique for the presence of rotavirus dsRNA in the Department of Medicine, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh, Bangladesh. The total prevalence of rotavirus infection in broiler chickens was in Gazipur 2.43% and 0% in Mymensingh. In the two specimens positive for avian rotavirus (ARV), identical and peculiar RNA patterns were observed and were not similar to those for groups A, D, or F, but partially similar to that of group G rotavirus, suggesting that these viruses may belong to novel rotavirus group. Additional studies on more numbers of strains obtained from different flocks will be necessary to substantiate the notable observation.
